-x + 2y = -1....when x = 15...so we sub in 15 for x and find y
-15 + 2y = -1
2y = -1 + 15
2y = 14
y = 14/2
y = 7 <==
<u>Answer:</u> B.
Step-by-step explanation:
Diameter = Radius divided by 2.
The volume formula of a sphere is V = 4/3 π r^3.
Radius of this problem = 7.5.
So, V = 4/3 π (7.5) ^3.
Once you "plug in" the radius and solve the equation, you get an answer of 1,766.3, rounded to the nearest tenth.
<u>Don't forget the inches cubed!</u>
<em>Hello!</em>
The new value is $ 22,9425 or just $ 23 in a more simplified size.
We need to calculate 25% of 30.59.
We will do this by turning 25 into tenths:
Now, we subtract that from 30,59.
30,59 - 7,6475
= 22,9425
So, the new value is $ 22,9425 or just $ 23 in a more simplified size.
